The Kardashev scale is a general method of classifying how technologically advanced a civilization is. It was first proposed in 1964 by the Soviet astronomer Nikolai Kardashev. The scale has three designated categories called Type I, II, and III. These are based on the amount of usable energy a civilization has at its disposal, and the degree of space colonization. In general terms, a Type I civilization has mastery of the resources of its home planet, Type II of its solar system, and Type III of its galaxy.
* Type I â€” a civilization that is able to harness all of the power available on a single planet â€” has approximately 1016 or 1017 W available. Earth specifically has an available power of 1.74 Ã—1017 W (174 petawatts). Kardashev's original definition was 4 Ã—1012 W â€” a "technological level close to the level presently attained on earth" (presently meaning 1964).
* Type II â€” a civilization that is able to harness all of the power available from a single star, approximately 4 Ã—1026 W. Again, this figure is variable; the Sun outputs approximately 3.86 Ã—1026 W. Kardashev's original definition was also 4 Ã—1026 W.
* Type III â€” a civilization that is able to harness all of the power available from a single galaxy, approximately 4 Ã—1037 W. This figure is extremely variable, since galaxies vary widely in size; the stated figure is the approximate power output of the Milky Way. Kardashev's original definition was also 4 Ã—1037 W.
However ,it has been argued that, because we cannot understand advanced civilizations, we cannot predict their behavior; thus, Kardashev's visualization may not reflect what will actually occur for an advanced civilization.

(Civilization level and their features)<own observe>
Type0 early
-learned about farming,get the fire,make the tools either from stone and lately from metals.They living as the small tribals community.They having language and religion believe first time.
Type0 middle
-learned about physiology,natural science,art,and philosophy.come up with the gun powder.,compass,sail ship,they can trading with each other civilization.
Type0 lately
-Industry revolution,learned about idealogy,politic and social. Many country were builded.
-Electronic age,the long range communication capable.Tall building capable.
-Atomic age,huge destruction weapon,atomic energy,invented computer,chemical rocket.artificial satellite,ICBM,man in near space,interplanetary probe. Deeply know in physics.
-Information revolution,internet,satellite communication,artificial intelligent.Becoming global civilization.Terrorism rise.attempt SETI program.

Type 2 (all included)
-Interstellar system colony,heavy use of star power,manipulated gravity field,escaped able from explode of the sun.Anti-matter energy used in space propulsion system,harnessing all resource of solar system.Teleportation transporter,faster than light communication and travel.

He said physicists generally looks for three types of civilization in extraterrestrial intelligence.

type 1: planetary. has ability to control anything planetary such as earthquakes, weather and so on. An example of such civilization is Buck Rogers. They harness energy from within the planet but i gather it would be anything except fossil fuel.

type 3: galactic. harness energy from billions of stars within the galaxy. The borg or star wars empire are such example.

he mentioned Q in another interview is of a type 4 which wasn't discussed (probably unknown or more sci-fi/imagination i think).

In relation to where we are and how long before we get to the next civilization, we are currently at type 0. we harness our energy from dead plants (oil and coal). we are about 100 years away from reaching type 1. Type 2 is about 5000 years away. Type 3 is more like 100,000 to a million years in the distant future.

one interesting note is he said 2001: space odyssey is the most authentic rendition of how type-3 ETs visit other civilizations. The aliens would create a robot that will exponentially replicate itself and position themselves in all the moons and wait for civilization in the galaxies to evolve. He said Kubrick deleted the 1st 5 mins of 2001 to make the movie more mystical.

> there are quite a few of his Interviews Listed on the aforementioned Link above too . . .

Thanks Yon (btw) . . .

Thanks too,i rather believed the classification that was made by these scientist,although its was based on our earth civilization modeling,but any outer advanced civilization can be seeing as the hominine.

The speed of the technology grown is different in different civilization,these is dual to the condition of one planet.
Example,when a planet is lack of resource and then the civilization is cooperation with each other,we believed these kind of civilization is the most faster growing rate.
